The former England spinner, who was appointed director of cricket at his former county after a chronic hip injury forced him to retire in 2007, has instilled a regime of professionalism at Edgbaston which has seen Warwickshire in the hunt for double silverware this season, with the CB40 final against Hampshire to come on September 15.

Giles is already involved in the England set-up as a selector and Graeme Welch, Warwickshire bowling coach, believes Giles would be the ideal replacement to Andy Flower when he decides to step down.

"I think Ash would be the ideal candidate for England," Welch said in the Daily Telegraph. "Ash knows the England scene well, he has his own ways but he has instilled the discipline that he got from playing for England into our side.

"He's got a good eye for a cricketer and he's not hidden the fact that he would love to do it and I actually think that he would do a very good job.

"You have got to cut your teeth as a coach somewhere and it's difficult to learn your trade at a big club like Warwickshire. But Ash has done an excellent job for us. He works tirelessly, he loves talking cricket.

"He's very disciplined. When I first came back to the club I thought we were being a bit harsh on the things that didn't matter, but over the years the team has evolved with its discipline, its punctuality and its professionalism."
